Can scientists study Earth's interior directly?
No.
100
Who was the one who came up with the hypothesis of the continental drift?
Alfred Wegener.
100
Do Earthquakes only occur on a fault line?
Yes. Only on a fault line.
100
Does a volcano only occur during a fault line?
No. Volcanoes do not occur on a fault line. Although it is possible for them to do it, it is not a direct production.
100
What Biblical thing do people think caused the continental drift?
The great Genesis flood.
200
What does scientist gather to learn about Earth's compositions?
Seismic Data.
200
Name the supercontinent before it split up.
Pangea.
200
What is a tsunami? What is it caused by?
A big wave. It is caused by a coastal earthquake.

Lava is outside of the Earth. Magma is inside of the Earth.What is the difference between lava and magma?

Lava is outside of the Earth. Magma is inside of the Earth.

200
How many layers are there on the Earth? 
Four.
300
What is the density of the Earth's crust?

About 2.7grams.

300
What is the continental drift?
It is when the great supercontinent split apart into many different continents. 
300
How do Earthquakes occur?
When fault lines interact with each other and slip.
300
If a crater and the land around it collapse after an eruption, a large depression called what forms?
A caldera.
300
What is a pyroclastic flow?
A mixture of deadly gasses.
400
Name all four of the Earth's layers.
The crust, mantle, outer core, and inner core.
400
What is a seafloor spreading? How is it caused?
A seafloor spreading is when the oceanic crust gets another layer added to it. It is caused by an underground volcano erupting lava.
400
What are the three types of Earthquake waves?
The primary, secondary, and surface wave.
400
Name at least for parts of the anatomy of a volcano
The lava flow, vent, crater, parasitic cone, throat, side vent, layers of lava and ash emitted by the volcano, branch pipe, magma chamber, and conduit pipe.
400
Which fault line comes straight through California?
The San Andreas fault line.
500
Name at least four different materials that are in the layers of Earth.
Iron, nickel, silicon, oxygen, magnesium, and solid rock.
500
Give three facts that prove that there was a continental drift.
There are crocodiles in both Africa & South America. There are identical fossils of dinosaurs and palm trees in both Africa & South America. There are ice glaciers in Africa. And there are rock beds on all of the continents.
500
Name all three of the types of the Earthquake faults. 
The normal fault, the reverse fault, and the strike-slip fault.
500

Name and describe the three types of volcanoes.

Cinder Cone, (small, cone-shaped.)

Composite, (large mountain with steep sloping flanks.)


Sheild, (broad mountain with steep sloping flanks.)

500
What is the difference between the lithosphere and Asthenosphere?
The lithosphere is made up of the crust and the upper part of the mantle. Whereas, asthenosphere is just the mantle.
